Beta Testing Information

Getting started with beta testing

Requirements for beta testing

Your Missing Link should bet at a minimum of version 1.2. If your Missing Link software version is less than 1.2, please update to the latest version before installing the beta software.

Installing Beta Software

  1. Navigate your browser to the Missing Link Software Update page
  2. You will now see a “beta code” box just above the updater button
  3. Enter one of the beta codes listed below and then click that update button
  4. Missing Link will now download and install the dinsync beta then it will reboot your Missing Link.

Reverting Back to the Main Release

  1. Back in the Software Update page, delete the text in the “beta code” box
  2. Press the updater button, Missing Link will swap back to the current release and reboot

Available Beta Releases

Beta Code: b_1.4

The 1.4 beta includes the following updates:

  • Tighter, more stable clock at higher PPQN values (like 24 PPQN, including MIDI and analog output). The the tighter clock requires more CPU which slows down the WiFi Network processes on boot. To make room in the CPU while the Network is coming on line, The Missing Link will not output clock until the message on the screen stops saying “Starting Up Network.”
  • New Menu Item: AP Mode Ability to force the Access Point to always come on at boot, or never come on at all.
  • Web Control Panel: Access Point Settings
    • Change SSID/Name
    • Change Password
    • Allow SSID to be hidden from Wifi menu
  • New Menu Item: AP Settings Reset New menu item to revert customized AP Settings back to defaults (useful if you hid your SSID and can’t remember its new name). Since this requires a reboot, the menu works like this: Click the encoder button until you get to AP Settings Reset, then turn the encoder to the right 6 clicks and The Missing Link will reboot. AP Settings will revert back to SSID of MissingLink-xxxx, password of link1234 and Hidden SSID will not be checked.
  • New Menu Item: Reboot Missing Link Changing AP Mode requires The Missing Link to be rebooted. I didn’t want The Missing Link to reboot immediately after changing AP Mode as that wouldn’t be too usable. So it is a two-step process… change AP Mode, then go to Reboot menu and scroll to the right until The Missing Link reboot.

Things To Test

  • Clock stability Are you seeing any different behavior in the devices you are clocking? Skipping beats, falling out of sync? If you use lower PPQN values like 2 or 4, there shouldn’t be much impact. Let me know if you do see anything strange!
  • AP Mode Do the new AP Mode options (AUTO/ON/OFF) make sense and work as you’d expect? Is this useful to you? Do you experience any unexpected behaviors like not being able to get Link devices to talk to each other?
  • AP Mode: ON Force an Access Point by setting AP Mode to ON and rebooting The Missing Link. Test using The Missing Link in this mode. Do you experience any wonkiness with Ableton Link devices that are connected to The Missing Link’s Access Point? Any other issues? Is the Web Control Panel accessible via web browser, or is it not found?
  • Does this new Access Point Settings page in the web control panel work as expected? Does checking the Hidden SSID option actually hide your Access Point from your computer/phone’s WiFi menu? Does switching it back to not hidden work as expected?
  • Does the AP Settings Reset menu revert your Access Point back to its defaults?
  • Boot time: Are you seeing much longer times to boot up, get on a network (or spin up an Access Point) and get playing?

Known Issues

  • Setting AP Mode to ON There seems to be some sluggishness in the Web Control Panel coming online if The Missing Link has a local WiFi network it can connect to but it is forced in to Access Point Mode. I think the network has some remnants of the WiFi connection after the access point is spun up. I’m still looking in to this. Doesn’t seem to effect Link performance, but please try on your system to see if this is an issue.

Beta Code: clock

The clock beta tests the idea of MIDI Clock Sync input to The Missing Link getting broadcast to the Link peer network.

Steps to Test

  1. With The Missing Link powered off, plug Micro USB cable from USB port of Missing Link to a USB port on your DAW’s computer (e.g. MainStage). Note: No need to also power The Missing Link via its USB power supply. The computer should supply enough power over the USB port.
  2. Enable MIDI Sync output to the Missing Link from your DAW. It will be listed as USB MIDI Gadget in your DAW’s MIDI settings.
  3. Enable Link on Ableton Live or other Link devices to share the tempo coming from The Missing Link that is synced to your DAW.

Known Issues

  • Tempo fluctuates I am not sure where the fluctuations are happening. It might be a limitation of MIDI input to the Linux system… It could get deprioritized in the system and clocks may arrive late. We should be able add some logic to remove outliers if the tempo drifts sporadically (ignore tempo changes unless it seems to be settled there) I’ve added some smoothing and clock drop detection in hopes of smoothing most of the tempo fluctuations out.
  • No user settings Currently there are no user settings for MIDI clock input. If a clock is present, it will sync to that. Ultimately it would probably be good to have an option to ignore incoming sync. What other options would you like?
